SPECIFICATION forming part of Letters Patent No. 263,882, dated September 5, 1882,

Application filed July 17, 1882. (Model.)

To all whom it may concern:

Be it known that 1,0wnN F. Evans, of Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Improvement inStove-Tops, of which the following is a full, clear, and exact description.

My invention consists ot' the construction of the long cross-pieces of cook-stove tops, in a novel arrangement oldouble plates, with spaces between the platescalculated to afford protection of the upper and supportingplate from the heat, and thereby more eti'ectually prevent the bending of the same by the heat than as at present arranged, as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of a crosspiece constructed according to my invention. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is a transverse section otFig. 2 on the line am, and looking in the direction indicated by the arrows. Fig. 4 is a transverse section ot' Fig. 2 on the line g/ y, also in the direction of the Fig. 5 is a plan ofthe end section of the lower plate inverted. Fig. 6 is a plan of part of the middle section otl the lower plate inverted, and Fig. 7 is a plan of a portion ot' the upper plate inverted.

My invention relates more particularly to the long crosspiece, in which I make the top plate, a, of the usual form on the upper surface, but without the usual ledges, for the support ot' the ends ot' the short pieces, and only with portions c of the cover-supporting ledges, also with end flanges d to rest on the permanent ledges of the stove-top, and also with longitudinal side flanges or ribs, e, and middle rib,f, for strengthening it. The ribf has a depression at the middle of the plate, where a short transverse rib, g, of less depth than the longitudinal ribs, but of greater breadth, is located, aud both the side and middle ribs are reduced in depth at and from the section-line w to their ends, which terminate short ot' the end danges d of the top plate. To the under side of the plate thus formed I apply an under plate in three sections, h and it', for its protection from the heat, said plate being bolted -for the short cross-piece.

to it by three bolts,j, but being stopped a suitable distance below it, and the ribs e f for an ecient air-space between the two parts by the studs 7c and flanges Z, said studs being small as is consistent with the strength required to prevent as much as possible the heat from being conductedV to plate c. The sections 't' ot the said bottom plate have the parts m of the cover-ledges formed on them', While the side edges ot' section h form the ledges b The end sections 'i of the lower plate have depressed corners n to bear under ledges c ot' the plate c to support them and protect them from the heat. The middle section, h, of the lower plate overlaps the ends of the short sections t' at points o, where the ribs f are narrowed to make room for them above the ends of section h, and the end flanges l of the end sections t terminate sufficiently short ot' the end ianges d of the top plate to prevent any injurious effect on the top plate by longitudinal expansion ot' the lower plate, both at the ends ot the latter and at the connecting-bolts.

New it will be seen that by the sectional arrangement of the lower plate it will bend much less itself than it would if in one piece; that it will not bend the top plate; that by having the ledges mainly on it for the support of the short cross-piece and the covers the top plate is more eiectually protected from the heat, and that in consequence of the air-space between the two parts of the plate the top part will Ilot be heated to such extent as to cause it to bend.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, in along cross-piece for stove-tops, ot a top plate, a, and a lower plate consisting of three sections, h i t', the said plates being connected together, with a separating air-space between them, substantiallyr as described.

2. The combination, with the top plate, c, ot' 9:

a long cross-piece for stove-tops, of an under plate consisting of three sections,-lt and i i, said under plate having the ledges b for the short cross-piece, also ledges m, for the covers,

and also the separating-studs 7c and flanges Z, and said upper and lower plates being bolted together, substantially as described.

3. The long cross-piece for a stove-top, consisting of top plate, a, having end anges d, cover-ledges c, and side and middle ribs, ej', in combination with a lower plate consisting ot three sections, la, and i i, said lower plate having separating-studs and anges lo l, and the cover and cross-piece ledges m and b, substantially as described.

4. The end 'sections i, having depressed corners n, in combination with top plate, a, and cover-ledges c thereof, substantially as described.

5. The long crosspiece for a stove-top, consisting of top plate, a, having end flanges d,
